Fast SAXS Profile Computation with Debye Formula

Type PDB code of input molecule or upload files in PDB format (zip file with several PDBs can be uploaded):

Input Molecule: (PDB:chainId e.g. 6lyz:A) or upload file:
Experimental profile: (optional) sample input
e-mail address: (optional, the results are sent to this address)

Advanced Options

[Show][Hide]

Maximal q Value
Profile Size # of points in the computed profile
Hydration Layer use hydration layer to improve fitting
Excluded Volume Adjustment adjust the protein excluded volume to improve fitting
Implicit Hydrogens implicitly consider hydrogen atoms
Background Adjustment adjust the background of the experimental profile
Residue Level Computation perform coarse grained profile computation for Ca atoms only
Offset use offset in profile fitting

NEW! Search for Minimal Ensemble (MES) when you upload multiple PDB files.
NEW! Interactive display for profile plots and input structures.
